Feliks should be qualifying in the top 10 on the grid
My proposal it is modified poped valve which let for very effective picking up the warmth by chilling with intense stream of oil.
Thanks to widening the leading part of the valve to the maximum dimension which can only to fit in the nest , the surface of the joint of the valve with the head repeatedly was increased.
Thanks to widening the leading part of the valve to the maximum dimension which can only to fit in the nest the surface of the joint of the valve with the head repeatedly was increased. much simpler sailing across the warmth causes it to the well chilled head. a here also omitted Valve Guide which is usually of materials worse being a heat conductor than aluminium stayed. the additional crack of the baulk still became the Valve Guide to head liquidated in this new structure of the valve. The new structure allows to move heat to the head very efficiently. with valve quide omitting, and big relatively with area.
In the new structure it is an important thing, that inside valve on 3 / 4 one's length is feeling empty inside and has the enormous area for the exchange of the warm with chilling oil.
Chilling jst oil passed to the middle of the valve with the help of two tubes from which the very intense stream of cooling oil is flowing out.

I think that at such a construction of the valve, the temperature of the valve should not exceed 500 degrees Celsius, and NOx coming into existence in a combustion chamber can be limited about about 80 %

It will also be possible to increase the efficiency of the engine by increasing the degree of tensing, or else there will be no great temperature in a combustion chamber what the significant reduction of self-ignitions will cause, and will cause more laminar burning.

And the most important case. Since temperature of the new valve on 3 / 4 his lengths she should not be bigger than the temperature of the head, it will be possible to resign entirely from devices for placing valve clearance, since the sum of the expandability of the new valve and the expandability of the head will be approximately similar.

therefore keeping valve clearance of manner will be unnecessary as a result of the same complete expandability of the valve and the head.

Below I am describing two models of the latest version of valves, and the disintegration of the temperature on the length in the traditional valve.









Happy New Year Andrew
